Application filed February 18, I907. Serial No. 368,041.

To all whom it may concern.-

Be it known that I, HARVEY L. HOOKE, a citizen of the United States, anda resident of Muncie, in the county of Delaware and State of Indiana,have invented a new and useful Device for Controlling Motor-Cars, ofwhich the following is a'specification.

This invention has reference to devices for controlling the speed andthe direction of movement, forward or rearward, of motorcars.

The invention is shown herein embodied in a device for controlling, inmotor-cars, the mechanisms transmitting the motive power therein to'thetraction mechanisms. In motor-cars of the preferred type the gearing isso arranged that three differential speeds of the car forwardly, and thereversal of the di rection of movement .of the car, may be accom lished.

T e features of this invention consist essentially of a control-leverpivotally mounted so that it may be oscillated between op o- 'sitelypositionedsector-plates, the latter eing supported by a suitable frameto be secured to the frame-work of the motor-car;

and two cranks having hollow shafts for con.

ditiously and positively accomplished; and

whereby the crank that is in engagement withthe transmission not inactual engagement is automatically locked securely in inoperativeposition.

Another featurev of the invention is the novel combination with thedevices referred to of a shaft which is adapted to be connected to theemergencybrake mechanism of the car, journaled to the said sector-frame,the lever for the oscillation of this shaft being secured directly toit, and retaining means therefor secured to and made a part of the saidsectorframe.

The object of this invention is to provide a device to accomplish the enagement or disengagement of either of the differential speedgears fordriving the car forward, or for reversing the movement of the car, andto provide. such device so improved in arrangement, conformation andconstruction of its parts that it will be neat and of good appearance,com act, of few parts, and not liable to get out 0 adjustment or repair,and whichmay be exceedingly simple and easy of manipulation.

A further object is to combine therewith an emergency brake mechanism insuch'man- 6 5 erence refer to corresponding plarts throughout theseveral views, in wlrn Figure 1 is a front view, and Fig. 2 is a sideview of my newly invented device complete, the control-lever being setin neutral position. view taken on the line 33 Fig. 1. Fig. 4 is anenlarged central transverse sectional View of the invention as shown inFig. 1, the extended portions of the levers and the frame- Fig. 3 is atransverse sectional plate being broken away, and the shafts being 8 5roken into. Fig. 5 isa detached enlarge central transverse sectionalview of the heads of the control-cranks and'the main'portion of thecontrol-levenas the same are shown in Fig. 1, the control-lever being inengagement 0 with the control-crank G, the plunger 1n the control-leverhaving been depressed its full stroke. Fig. 6 is a front view of thedevice, the extended portions of the levers having been broken away, thecontrol-lever being 111 engagement with the control-crank H, and shiftedfrom neutral position. Fig. 7 is a front view of the device, theextended portions of the levers having been broken away,

Fig. 8 is a detached e argedtransverse sectional view taken on the line 8-8 Fig. 6, and Fig. 9 is atransverse sectional view taken on the line 9-9 Fi .7. Fig.

. 10 and Fig. 11 are detached enlarge perspective views of thecontrol-cranks H and G,

respectively, the extended portions of the posed of the body-portion Ahaving a transverse aperture A therethrough and the plate A formedintegral therewith provided with the holes A through which suitablebolts are assed to secure the frame to the motor-car;

ormed integral with the body-portion A and disposed with their endsapart and in accurate position are the arms A finished on their ends toreceive on their front and rear sides, the sector-plates B and C whichare rigidly secured in position by the bolts D. Immediately back of thefrontal heads of the bolts D is the curvilinear rack-bar E retainedparallel to and a proper distance apart from the sector-plate B, by therings D.

The sector-plates B and C are rovided with suitable horizontal flanges oproper width so that the continuous slot F is formed, in which slot thecontrol-lever I may be freely oscillated. In the under-side of theflange of the sector-plate B at a point equidistant from its ends, isthe transverse recess B the function of which will be presentlydisclosed. Formed integrally with the vertical portion of thesector-plate C and extending concentrically with the flange thereof, isthe ledge C its continuity being broken by the opening C at a pointequidistant from its ends. At the central point longitudinally of thelower edges of each of the sectorlates are the angular recesses B and Cas p ainly shown in Fig. 6 and Fig. 7.

Referring to Fig. 4; G and H designate control-cranks, having the hollowshafts G- and H respectively, formed integral therewith, of suitablelengths to receive on their extended portions suitable connections forthe transmission devices to be actuated; the 'hollow shaft Gr beingjournaled in the aper-i tureA "and the hollow shaft H being 'our naledin the hollow shaft G These s afts are intended to be of roper lengthsas may be desired. Journale on the hollow shaft H and retained betweenthe cranks G and H,.

' ence to Figs. 4, 5, 10 and 11 of the drawings.

The control-crank is of such length that in its oscillation, its head,which is disposed imsuitable well provided therefor.

tained the detent K having the shoulder K adapted to engage the recess CThis detent K is provided with the slot K which engages the pin G5passed through and'rigidly secured in the head of the crank. Extendingdownwardly a suitable depth in the body I of the crank from the seat ofthe slot G is the well G in which resides the coil-spring K This slot Kis of such depth and the in G is so positioned in the head of this cranthat by the upward pressure of the coil-s ring K against the end of theshank K the etent K i is normally retained yieldingly in the position asshown in Fi 4 and Fig. 11.

The control-crank H is of such len th that in its oscillation, its head,which is isposed immediately'beneath the flange of the sector-plate Bwill pass freely thereunder; the

outer face of this head is provided with the shoulder H and theface-plate H which engage the lower edge and outer face, respectively,of the sector-plate B, and slidingly retain the head of this crank incorrect transverse position. It-will be observed that the vertical lineof the inner face of the head of this control-crank H is within thevertical line of the inner edge of the flange of the sector-plate B thedistance measured by the transverse tongues H rotruding from the innerface of the head 0 the crank.

H designates a transverse slot of proper de th and in which the pawl Lsnugly resi es and is pivoted on the in H passed through and rigidlysecured 1n the head of this crank. This pawl has the shank L, the face Lthe dent L and the nose L", the functions of each of which parts will bepresently disclosed. This .pawl is yieldingly maintained in the positionas shown in Fig. 5 by the pressure upwardly of the coil-spring L againstthe stu L which has its bearing in the dent L and is slidingly retainedin a WVhen this awl L is in the position as shown in Fig. 4 it 1s soretained by the dog positioned in the control-lever to be presentlydescribed.

I'designates the control-lever positioned between the control-cranks andjournaled on the hollow-shaft H and is of such width ately above thisslot the body of the lever is continued in a line aside from the center,to a proper length where the handle I is formed integral therewith, asplainly shown in Fig. 1. I? designates a well in this handle openinginto the aperture I of smaller diameter and which passes through thehandle, as shown in Fig. 3; an aperture I of similar size is provided inthe portion I of this lever. Residing in the well I is the strongcoilspring M. The plunger M having a suitably finished fiat headthereon, and of proper length, has the plunger-rod N rigidly secured inits bottom; this plunger-r0 is slidingly retained in the apertures l andI and rigidly secured to its lower end is the dog 0 of such transversewidth as to fit snugly yet slidingly the slot P. The distance from theupper edge of the dog and the bottom edge of the plunger M is such thatwhen the dog is in the position as shown in Fig. 4, there will be aproper vertical clearance between the head of the plunger M and the topof the handle 1 This dog 0 is provided with the noses O and 0 adapted tooccupy the slots H and G respectively, alternately, and also to engagethe pawl L and the detent K, respectively, alternately. The foot 0 isprovided to lend stability thereto in the differ: cntial positionsoccupied by it, as shown in Fig. :1 and Fig. 5.

The brake-lever J rigidly secured to its shaft J, is extended in lengthas shown in Fig. 1 and at the enlarged portion is provided with asuitable slot which surrounds the ratchet-bar E.

J 2 designates the lock-bar which has suitable slot therein to surroundthe ratchetbar and to engage the ratchet-teeth on its under side; thislock-bar is slidingly secured in position by suitable means and isnormally held in engagement with the ratchetteeth and connected by thewell known means illustrated, to the handle J and the grip J, so thatthe lever may be locked in and unlocked from differential positions onthe ratchet-bar.

In assembling the device, the shaft G? is inserted through the apertureA of the frame,- then the sector-plate C is placed in position with itslower edge in engagement withthe head of the control-crank G, thecontrollever is then placed in position'and the shaft 11 is theninserted therethrough and through the hollow shaft G, then thesector-plate B is placed in position with its lower edge in engageim-ntwith the head of the control-.

crank H. The shaft J having the brakelever secured thereto is thenplaced in position as shown in Fig. 4, the ratchet-bar E insortedthrough the slot therefor, and the bolts binding the sector-plates, theframearms and the ratchet-bar together, are

placed in position, and when tightened, the

device is complete, and in readiness to be applied to use, and appearsas shown in Fig. 1. To readily understand the description of theoperation of my invention, reference may be had to Fig. 12 of thedrawings, wherein the device is shown secured to a frame-member of amotor-car, connecting bars P and Q being shown as'pivotally secured tocranks on the shafts G and H respectively, and which said connectionsengage the medium and high-speed gearing, (not shown), and the slow andreverse gearing (not shown), respectively, of the car. The connectingbar B, being shown as pivotally secured to a crank on the shaft J isadapted to engage the braking-mechanism (not shown), of the car.

When the entire gearing of the car is out of engagement and my inventionis not in action, the parts of the device, all, are in the positions 'asshown in Fig. 4; the dog O having its nose 0 held firmly in engagementwith the recess B and occupying the slot H of the control-crankv H, andthe detent K having its shoulder K in engagement with the recess C ofthe sector-plate C, the controlcrank G being thereby locked. When it isdesired to bring into action the slow speed gearing, the plunger isdepressed slightly whereby the dog ()is released from its engagementwith the recess B and the forward movement of the control-lever movesthe control-crank H and shaft H by the movement of the control-leverrearwardly it having'in engagement, the crank H, the reverse gearing isbrought into action. When I it is desired to bring into action themedium speed gearing, the control-lever is brought to the neutral, orcentral position; the plunger is then depressed its full stroke wherebythe nose 0 of the dog leaves its position in the slot H of thecontrol-crank H and slidingly engages the face L of the pawl and forcesits nose L directly into engagement with the recess B of thesector-plate B, thereby locking in immovable position, the control-crankH; at the same time the nose 0 has passed through the opening C cominginto occupancy of the slot G of the cone trol-crank G and disengagingthe shoulder K of the detent, from the recess C thereby locking1 thecontrol-crank G into engagement. with t e control-lever and unlocking itfrom the sector plate C; the hand of the operator is held on theplunger-head and the controllever is moved forwardly from its neutralposition. When it is desired to bring into ac tion the high-speedgearing the controllever (the plunger being held clown to lowermostposition, as the line of neutrality is passed) is thrown rearwardly. I
